[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The present invention provides a heating and forming groove rolling machine for press fittings, such as Figure 1-6 As shown, the machine comprises a chassis 1, on which are arranged in sequence a loading component 2, a heating component 3, a troughing component 4, a grooving component 5, and a finishing component 6. Each component corresponds to a corresponding workstation. During operation, a workpiece, under the action of a manipulator assembly 8, passes through the loading component 2, the heating component 3, the troughing component 4, the grooving component 5, and the finishing component 6 in sequence, completing processing in one go. During processing, a soundproof cover 9 is provided on the upper portion of the chassis 1, and each component is enclosed in the soundproof cover 9 to reduce the interference of processing noise on the external environment. A manipulator assembly 8 is provided between the loading component 2 and the heating component 3, between the heating component 3 and the troughing component 4, between the troughing component 4 and the grooving component 5, and between the grooving component 5 and the finishing component 6. A gantry 7 is provided on the chassis 1. The manipulator assembly 8 is mounted on the crossbeam of the gantry 7 within the span of the heating component 3, the troughing component 4, the grooving component 5, and the finishing component 6.

[0033] One embodiment of the loading component 2 in the present invention is as follows: the loading component 2 includes a first driving device, a loading conveyor belt 21, a loading support frame 22, a loading electric cylinder 23, and a loading clamping claw 24. The loading conveyor belt 21 is installed on the chassis 1 and is driven by the first driving device. The loading support frame 22 is installed on one side of the output end of the loading conveyor belt 21. The loading electric cylinder 23 is installed on the loading support frame 22 and is parallel to the conveying direction of the loading conveyor belt 21. A support plate 25 is provided on the loading support frame 22. The loading claw is slidably installed on the support plate 25. One side of the loading claw is rotatably connected to the output end of the loading electric cylinder 23. One end of the loading claw extends to the top of the loading conveyor belt 21. The blanks of the workpieces are arranged in sequence. The workpiece blank is placed on the loading conveyor belt 21 in a vertical state with one end to be processed facing upward on the loading conveyor belt 21. A slide 26 is provided on the support plate 25, and one end of the loading claw is slidably connected to the slide 26. One end of the slide 26 is provided with a vertical groove 27 perpendicular to the slide 26. There is a smooth transition between the vertical groove 27 and the slide 26. The workpiece clamped by the loading claw is horizontal in the slide 26. The loading claw first grabs the vertical workpiece blank, and then under the pushing action of the loading electric cylinder 23, the loading claw moves along the slide 26. When the loading claw moves to the position of the vertical groove 27, it will rotate under the action of the thrust, thereby causing the workpiece blank to rotate to a horizontal state. At this time, the workpiece blank can be grabbed and transported by the robot assembly 8.

[0034] The horizontal workpiece blank will be transferred to the heating component 3 under the action of the manipulator assembly 8, wherein the heating component 3 is used to heat the blank end of the pipe fitting to soften the pipe fitting end. The heating component 3 includes a first seat body 31, a first positioning fixture 32, and a high-frequency heating machine 33. The first positioning fixture 32 is installed on the first seat body 31, and the high-frequency heating machine 33 is provided with an electric heating wire 36. The high-frequency heating machine 33 is fixed on the high-frequency linear rail seat 34, and one end of the high-frequency linear rail seat 34 is connected to a heating drive cylinder 35; one end of the workpiece blank will be fixed on the first positioning fixture 32, and the heating drive cylinder 35 controls the sliding of the high-frequency heating machine 33 through the servo mechanism, so that the electric heating wire 36 is close to one end of the workpiece for heating. The purpose of heating is: 1) to reduce the mechanical force of the pier groove station, 2) since the workpiece blank has soft and hard states, the soft part can be more easily formed with the mold cavity, which is convenient for subsequent pier groove processing. A heat insulation plate is provided on the side of the first base body 31 facing the electric heating wire 36 to prevent damage to the first base body 31 caused by prolonged and frequent heating. A cooling system is provided at the location of the heating component to ensure a constant temperature state of the component during the heating process and avoid deformation caused by prolonged heating.

[0035] The heated workpiece blank is transported to the pier groove component 4 through the manipulator assembly 8, wherein the pier groove component 4 includes a pier groove electric cylinder 41, a connecting rod 42, and a punch 43. One end of the connecting rod 42 is connected to the output end of the pier groove electric cylinder 41. The punch 43 is installed at the end of the connecting rod 42. The punch 43 extrude the end of the pipe after being softened by the heating component 3 and forms a pressing groove. The pier groove component 4 also includes a second base body 44, a pier groove mold, and a second drive device 45. The pier groove mold includes an upper mold 46 and a lower mold 47. The lower mold 47 is fixed on the second base body 44, and the upper mold 46 is slidably installed. On the base body and directly above the lower die 47, the second drive device 45 is installed above the second base body 44 and connected to the upper die 46, and a pressing cavity 48 is provided in the pier groove mold; the manipulator assembly 8 places the workpiece blank in the lower die 47, and then the second drive device 45 drives the upper die 46 to close the mold, fix the workpiece blank through the pier groove mold, and then extrude the workpiece blank through the punch 43. Since the port part of the blank becomes soft after heating, a pressing groove on the pipe fitting can be formed under the combined action of the extrusion of the punch 43 and the pressing cavity 48 of the pier groove mold, and the forming of the pressing groove is completed at this time.

[0036] The robot assembly 8 transports the workpiece with the pressing groove formed thereon to the grooving component 5, wherein the grooving component 5 is used to ensure the uniformity of the internal dimensions of the convex groove; the grooving component 5 includes a grooving head 51, which can be extended into the pressing groove and roll the pressing groove. The grooving head 51 is driven by the grooving spindle box 52, and can realize movement in the X / Y / Z directions, thereby rolling the pressing groove.

[0037] The finishing component 6 is used to ensure the consistency of the product socket size and eliminate the dimensional instability factors of the blank turning process. The finishing component 6 includes a cutting spindle box 62 and a cutting head 61. The cutting head 61 is installed on the cutting spindle box 62. The cutting head 61 finishes the inner wall of the pressing groove after rolling (this can be understood as a boring process).

[0038] It should be noted that, during the specific production of this application, each workstation can perform processing simultaneously, realizing assembly line processing and improving production efficiency.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
